V8-22 Module has 22 Total Advance all in by 4500rpm.
V8-20R Module has 20 Total Advance all in by 5250 RPM.
Therefore, I would not recommend the V8-20R module. It's got a super slow azz curve.
This is according to my notes. Which I'm sharing to you for free. Thus, if I'm wrong, I owe you nothing. LOL.
